> Currently hbase provides a metric for [number of total active rpc
> handlers|https://github.com/apache/hbase/blob/f4f2b68238a094d7b1931dc8b7939742ccbb2b57/hbase-server/src/main/java/org/apache/hadoop/hbase/ipc/SimpleRpcScheduler.java#L187]
> which is a sum of the following:
> * number of active general rpc handlers
> * number of active priority rpc handlers
> * number of active replication rpc handlers
> I think we can have 3 different metrics corresponding to the above mentioned
> handlers which will allow us to see detailed information about number of
> active handlers running for a particular type of handler.
> We can have following new metrics:
> * numActiveGeneralHandler
> * numActivePriorityHandler
> * numActiveReplicationHandler
>
